    Default When is a Brick a Brick? 3GS Super Stuck in Recovery Mode - Clues but no definites

    When is it time to give up on a 3Gs

    So a couple weeks back I bought an iphone 3Gs 16gig at a Customs and Police seizure auction. I put a blind bid in and won so I was both happy and nervous. Happy because I won and nervous because I didn't get to see it before the buy. When I got it home I was glad to see the screen come to life with the 'Plug into iTunes' screen so there was relief in knowing that it had some life. Now I have been out of the jailbreak and unlock scene for about a year but I imagined that I would be able to figure it out if it needed to be unlocked. See, Im here in New Zealand where all phones are unlocked, but at a police auction you never know what you are going to get.

    So through quite a few hours of trial and error I have come to the conclusion that this phone must have been coked at one point. It is currently stuck in Recovery mode but through tny umbrella i managed to get a glimpse of some greenpois0n code. I have tried most of the various methods for forcing the 3GS out of Recovery mode. I have tried using iRecovery, Limera1n, Blackra1n, Redsnow, Pwnage Tools of various versions and even let over to a PC to try using iREB, Sn0wbreeze and reformatting from a iTunes in the PC. Greenp0ison is the only one that actually gets a reaction but it is fruitless.

    I have come to the conclusion that this iPhone 3GS must have been unlocked using the Ipad Baseband and is currently stuck in Recovery mode with nothing but rejections from iTunes when i try and use custom firmware (or any firmware for that matter). I even tried to stop itunes from calling home and just calling locally but I didn't do that right so far and that is what I will try and do correctly next. The reality is im probably 9 hours deep total and I personally don't know when to quit. So I need some advice. Do I quite? Am I missing something? Thoughts? I am hoping that someone will say ' hey stupid you are missing this, this and this' but Im not that optimistic. Suggestions? Give Up?

    Also:

    iBoot-931.71.16 (4.2 GM and 4.2.1 Builds 8C148, 8C148a, and 8C154)

    Also, got a bit more info out of it.

    Have you not managed to get it into DFU mode? Does it charge at all?

    I Olethros,

    I have managed to get it into DFU, Tried Fix REcovery in Tiny Umbrella, Tried Custom IPSW in iTunes in DFU and Recovery Modes as well. Check out this screen shot of tiny umbrella though. It recognizes the device but gives no info.

    Also, does not ever show that it is charging.

    Can you post a screenshot of what SystemProfiler shows about the device when it is in DFU mode?

    This can point to a hardware problem

    However it is also true that the phone doesn't charge when in some bootloop/partly booted states. If that is the case, when the phone fully boots it will charge again normally.

    SO we need to work out exactly what state it is in right now (doesn't look like DFU from the screenshot you posted)

    I have to say this was quite a major deal and as I stated in the begining I was sure the iphone was too far gone. However, I found another person with the same issue and we got it sorted out.

    The culprit for my problems was TinyUmbrella, I'm not sure if it's a feature (or setting toggle) that they added (or made default) in the latest version or not but it's very simple. Open up TinyUmbrella and go to the Advanced tab, when there uncheck the following option:

    "Set hosts to Cydia on exit"

    While TinyUmbrella is open it sets all hosts to ping the Cydia servers rather than the Apple ones (at least in my experience) which is why you shouldn't do a restore/update while TinyUmbrella is open. If the above setting is enabled then it keeps those settings even if TinyUmbrella is closed.

    So, in a nutshell here are the steps I did to fix my issue.

    1. Fired up TinyUmbrella and changed the above mentioned setting
    2. Closed TinyUmbrella
    3. Fired up iTunes and ran a normal restore (of course since it was an iPad BaseBand it failed and put me into recovery mode, I did this to get out of the DFU/Greenpois0n loop I was stuck in)
    4. Fired up Pwnagetool 4.3.3 and created a fresh custom 4.3.3 IPSW (I got the IPSW file from iTunes)((I also got rid of the previous ones I had made as they were corrupted)).
    5. Using Pwnagetool, put the device into pwned DFU mode.
    6. Went back into iTunes and custom restored to the custom 4.3.3 IPSW Pwnagetool created.
    7. I laughed hysterically as the restore completed successfully!

    This took my phone from the depths of despair:

    To Success.

    Thanks for trying to help!

    Glad you worked it out in the end, I guess we mis-understood your original description-

    The "uncheck set hosts to Cydia on exit" will only help in one of the following situations:

    • You have an iPhone 4 (and the restore/upgrade/downgrade tries to change or reload your baseband)
    • Restoring from pwned DFU mode and you don't have a SHSH saved with Cydia for the iOS version you are trying to restore
    • Cydia's TSS proxy service is malfunctioning and returns an incomplete or invalid SHSH for the iOS version you are trying to restore (very unlikely)
    • Cydia's TSS server wasn't yet handling correctly requests for SHSH blobs for the latest iOS version (this was definitely a problem with 4.3.3 up to a day or two ago)


    The last option was most likely the explanation for why "uncheck set hosts to Cydia on exit" fixed your problem. I believe that Cydia's SHSH proxy can now handle requests for 4.3.3

    There was no indication in your original post that the baseband had been updated to the iPad baseband.
